DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific drawings.

[0022] Referring to Figure 1 A preferred embodiment of a high-precision weighing and sub-packaging device, in this embodiment, the high-precision weighing and sub-packaging device is used for weighing and assisting in sub-packaging of health-care tea containing eight different components, so as to realize accurate proportioning and sub-packaging.

[0023] The main body of the high-precision weighing and sub-packaging device is a material distributor 6, which comprises a structurally closed stainless steel shell. The top of the stainless steel shell is open and can be closed and sealed by a bin cover 1 with an inner sealing ring in the open position.

[0024] The material distributor 6 is supported and positioned by a device support (not labeled). In different embodiments, the device support can be made of different materials and have different structural designs to meet different usage environments and requirements. The device support is provided with a fixing buckle, and the fixing buckle is further formed with a rubber pad on the inner side of the material distributor abutting portion. Through the fixing buckle, the material distributor 6 can be stably abutted on the device support, and the rubber pad can realize shock absorption and buffering in the running state of the device. When the fixing buckle is loosened, the material distributor 6 can be removed as a whole to facilitate cleaning and maintenance.

[0025] The inside of the material distributor 6 is a hollow structure. The upper part of the hollow structure corresponds to the bin 4, and the bin 4 is provided with a storage grid assembly position in the length direction in the same plane. Correspondingly, eight storage grids 3 are detachably assembled on the storage grid assembly position. The eight storage grids 3 are respectively used for storing raw materials of eight different components of health tea and discharging the raw materials. The two adjacent storage grids 3 among the eight storage grids 3 and the inner wall side wall of the bin 4 are tightly connected and fixed in position by the plug-in buckle 5, so as to ensure that the storage grid 3 will not be displaced in the bin 4 during the sub-packaging process. In addition, the plug-in buckle 5 can also enable the single storage grid 3 to be independently disassembled in the bin 4, and the rapid replacement and replenishment of the material can be easily realized by disassembling the storage grid 3.

[0026] A cover plate 2 with a sealing structure is installed at the top opening of each storage grid 3 to prevent the material from being contaminated by the outside during storage and sub-packaging. In addition, a hollow interlayer is also provided in the storage grid 3, which is used to place a hygroscopic agent consumable to keep the material dry and avoid deterioration of the material or decrease of the sub-packaging precision due to moisture absorption.

[0027] In other embodiments, the number of storage grids 3 and the volume of a single storage grid can be adjusted according to actual needs to adapt to different types and quantities of raw material components. For example, for health tea with only three raw material components, the number of storage grids can be correspondingly reduced to save cost and space. When the number of storage grids 3 is large, the one-dimensional structure arrangement of the present embodiment can also be replaced by a ring-shaped arrangement or an array arrangement in the planar space of the bin 4. In addition, the plug-in buckle 5 can also be replaced by other forms of fixed connection, such as hole insertion, to adapt to different usage environments and requirements.

[0028] At the bottom of each storage compartment 3, a discharging structure is provided, which includes a discharging pipeline 7, and a spherical buffer cavity 8 is connected in series on the discharging pipeline 7. The spherical buffer cavity 8 is made of a deformed material and is internally provided with a pressure sensor for detecting and adjusting the pressure in the discharging pipeline to ensure the stability and uniformity of the material during discharging. The structural design of the spherical buffer cavity 8 can effectively absorb the impact force generated during discharging, reduce the breaking and layering of the material during flow, and thus improve the accuracy and efficiency of the dispensing.

[0029] The lower part of the spherical buffer cavity 8 is placed on a ring-shaped base 9 with a primary weighing device. An electromagnetic valve is also provided on the discharging pipeline 7 and is used in cooperation with the primary weighing device. The primary weighing device is used to weigh the amount of material discharged when the electromagnetic valve is opened to achieve precise control of the material in the corresponding storage compartment 3. The primary weighing device includes a weighing sensor for real-time monitoring of the weight of the material and a control unit for automatically adjusting the opening and closing of the electromagnetic valve according to the set dispensing parameters to achieve precise dispensing.

[0030] Below the ring-shaped base 9, a mixing hopper 11 is provided, which is internally formed with an inner bowl 10. The inner bowl 10 is independently formed and can be detached in the mixing hopper 11. The inner bowl 10 is connected with the driving shaft of the motor through a quick-mount base and is driven by the motor to rotate in the mixing hopper 11. In addition, stirring paddles are formed on the inner side wall of the inner bowl 10. These stirring paddles can mix and stir the materials respectively poured into the inner bowl 10 through the eight storage compartments 3 during the rotation of the inner bowl 10 to ensure the uniformity of the materials before dispensing.

[0031] The mixing hopper 11 is a free structure and is directly placed on a ring-shaped base 12 with a secondary weighing device and can be accurately weighed by the secondary weighing device.

[0032] The lower part of the inner bowl 10 is formed with a mixing hopper discharge port 13 connected to the mixing hopper 11. The mixing hopper discharge port 13 is connected to a Y-shaped material falling pipe 14 at the lower part, and a reversing valve 15 is also provided on the Y-shaped material falling pipe 14. The reversing valve 15 can control the flow direction of the material in different directions according to the weighing result of the secondary weighing device to achieve the distribution and recovery of the material. Specifically:

[0033] When the mixed material in the inner bowl 10 is within the set threshold range as weighed by the secondary weighing device, the Y-shaped material falling pipe 14 controls the mixed material in the inner bowl 10 to fall into a dispensing hopper 18 through the reversing valve 15, and the dispensing hopper 18 enters the next process with the dispensing hopper conveyor belt 17;

[0034] When the mixture in the inner bowl cup 10 is out of the set threshold range, the Y-shaped dropping pipe 14 controls the mixture in the inner bowl cup 10 to drop into the recycling hopper 16 through the reversing valve 15, and the mixture in the recycling hopper 16 can be recycled periodically, and the recycled mixture is used for component screening and then returned to the corresponding storage compartment 3.

[0035] In another embodiment, a hose is installed at the bottom discharge port of the mixing hopper 11. The hose is vertically arranged and connected to the Y-shaped dropping pipe 14 equipped with the reversing valve 15 at the lower end of the hose. The hose serves as a dropping channel, and a ring sleeve connected to a vibrating mechanism is arranged above the hose to ensure smooth dropping. The vibrating mechanism provides vibration assistance during the dispensing process to facilitate continuous feeding of the material in the hose without material jamming, ensuring uniform dispensing. The introduction of the vibrating mechanism significantly improves the flowability of the material, making the dispensing process more uniform and efficient.

[0036] In this embodiment, the device further comprises a control unit for data communication and feedback control of the primary weighing device, the secondary weighing device, the reversing valve, and the electromagnetic valves in the device system. A touch screen operation panel connected to the control unit is also arranged on the equipment support. The operator can interact with the touch screen to set the dispensing parameters, start or stop the dispensing process, and monitor the dispensing status in real time.

[0037] When the device is in use, the parameters are set on the touch screen, including dispensing speed, dispensing accuracy, material type, etc. After the parameter setting is completed, the operator starts the dispensing program, and the control unit automatically controls the entire dispensing process according to the set parameters.

[0038] Firstly, the control unit controls the material in the storage compartment 3 to enter the discharge pipe 7 in sequence through the electromagnetic valve, and the spherical buffer cavity 8 controls the discharge amount of the corresponding material in the single storage compartment 3 under the monitoring of the primary weighing device; this process corresponds to the individual weighing process of each single material. Then, the material falls into the mixing hopper 11, and the inner bowl cup 10 rotates under the drive of the motor, and the stirring paddle mixes and stirs the material falling into the storage compartment 3 to ensure the uniformity of the material.

[0039] After the material is mixed uniformly, the secondary weighing device weighs the mixture in the inner bowl cup 10. If the weight of the mixture is within the set threshold range, the material falls into the sub-packaging hopper 18 through the reversing valve 15, and the sub-packaging hopper 18 enters the next process with the conveying belt 17 for packaging. If the weight of the mixture is not within the set threshold range, the material falls into the recycling hopper 16 for recycling, so as to realize recycling of the material and reduce waste. Specifically, the material in the recycling hopper 16 can be returned to the corresponding storage compartment 3 after screening, so as to realize recycling of the material.

[0040] The entire sub-packaging process is monitored and adjusted in real time by the control unit, so as to ensure the accuracy and efficiency of sub-packaging. The control unit can also record various data in the sub-packaging process, so as to facilitate subsequent quality tracking and analysis. The touch screen operation panel provides an intuitive operation interface, which is convenient for the operator to set parameters and monitor the state, so as to ensure the smooth progress of the sub-packaging process. Through the high-precision weighing and sub-packaging device, accurate control and efficient sub-packaging of various materials can be realized, so as to meet different production requirements.

It should be understood by those skilled in the art that the present application is not limited by the above examples, and the above examples and descriptions in the specification are only to illustrate the principles of the present application.
